PROTECTIONLTIP FOR OAR-BLADES. g

SPECIFICATION forming part of Letters Patent No. 301,903, dated July 15,1884.

Application filed March 19, 1884. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE W. LINGLE, a citizen of the United States,residing at Stryker, in the county of Williams and State of Ohio, haveinvented certainnew and use ful Improvements in Protection-Tips for Oar-Blades; and I do declare the following to be a full, clear, and exactdescription of the invention, such aswill enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters and figures ofreference marked thereon, which form a part of this specification.

My invention relates to guards or protection-tips for oar-blades, andhas for its object the provision of a tip adapted to be applied to anoar, and having suitable indentations to avoid formation of sharp anglesor corners in the tip;

To the accomplishment of the above my invention consists of the tipconstructed and applied to an oar-blade, substantially as hereinafterdescribed, and pointed out in the claims.

In the drawings, Figure 1 represents a tip as it appears in the blankbefore being applied to the oar-blade. Fig. 2 is a side elevation of thetip in position upon the blade, and Fig. 3 is a bottom plan view of thetip as it appears when in position upon the blade.

Similar letters of reference in the several drawings denote like parts.

Referring to the drawings, A represents the blank, made in the formshown, and having the cut-away portion a 1. at its sides and roundedends a".

The dotted lines b show .the points at which the sides are bent upwardwhen the blank is applied to the blade.

c 0 represent cuts or slits extending from the outer edges of the blankto points thatintersect the lines I). The slits a are in line with theside edges of the oar-blade.

d (1 represent .indentations formed in the blanks at the points occupiedby the lower corners of the blade when the latter is in position withinthe tip. l

The dotted lines (1 d represent the points at which the end portions ofthe blank are folded upon the blade.

6 f represent apertures formed in the side 'and end flaps of the blankfor the passage of rivets, whereby the tip is held in position upon theblade.

The blank, prepared as above described, is

applied to the oar-blade as follows: The end flaps,first being bentupward,have their sides bent against the sides of the blade, after whichthe side flaps are bent upward and into the position shown in Fig. 2.Rivets are now passed through the apertures e f and the oarblade. Whenthe tip is in position,thelower corners thereof will appear rounded,asshown in Fig. 2, the indented portions dbeing pressed into the wood ofthe oar, the bottoms of said indentations being, upon the dotted line m.

Said indented portions (1 serve to give arounded lower corner to thetip, whereby the tip is strengthened and sharp angles avoided, as willbe readily understood. 1

Modifications of the form of blank may be madeas, for instance, theout-away portions a a may be restored. Therefore I would have itunderstood that I do not limit myself to the exact form shown, but holdmyself at liberty to make such changes as fairly fall within the scopeof my invention.

I am aware of Patent No. 191,923, and do not claim the constructiontherein shown and described.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is.

1. Aprotection-tip for oar-blades, constructed substantially asdescribed,havingtransverse slits on a linewith the side edges of theoarblade, and indentations arranged between the inner ends of saidslits, substantially as de scribed, and for the purpose set forth.

2. A protection-tip for oar-blades, having transverse slits terminatingat their outer ends in cut-away portions, indentations ar-, rangedbetween the inner ends of said slits, and apertures for rivets,substantially as described, and for the purposes specified.

3. A protection-tip for oar-blades, having slits and apertures, the endsof the tip overlapping the central or body portion thereof, the same,substantially as described, and for substantially as shown anddescribed. the purpose set forth. 1o
